Re: [CMake] General question about variable scope.
So, a couple things:
string(TOUPPER ${lib} lib_upper)
> set(WITH_LIB_${lib_upper}_EXAMPLES "")
>
> This needs to be outside the foreach loop. It's getting reset to empty on
every iteration rather than accumulating results
list(APPEND ${WITH_LIB_${lib_upper}_EXAMPLES} ${CMAKE_MATCH_1})
>
> Don't de-reference the first argument, just use the variable name itself,
i.e.:
list(APPEND WITH_LIB_${lib_upper}_EXAMPLES ${CMAKE_MATCH_1})
This is also well suited to a function, which are generally preferred over
macros as it will avoid polluting the current variable scope with temporary
variables:
function(bsBuildLibExamples lib)
string(TOUPPER ${lib} lib_upper)
set(all_lib_examples)
get_cmake_property(all_vars VARIABLES)
foreach(var IN LISTS all_vars)
if(var MATCHES "^WITH_LIB_${lib_upper}_EXAMPLE_([A-Za-z]+)$")
list(APPEND all_lib_examples ${CMAKE_MATCH_1})
endif()
endforeach()
set(WITH_LIB_${lib_upper}_EXAMPLES "${all_lib_examples}" PARENT_SCOPE)
endmacro()

[CMake] General question about variable scope.
Hi everyone,
i've the following code:
macro(bsBuildLibExamples lib)
# get all examples
get_cmake_property(_vars VARIABLES)
foreach(_var ${_vars})
string(TOUPPER ${lib} lib_upper)
set(WITH_LIB_${lib_upper}_EXAMPLES "")
if(_var MATCHES "^WITH_LIB_${lib_upper}_EXAMPLE_([A-Za-z]+)$")
message(STATUS "Example found: ${CMAKE_MATCH_1}")
list(APPEND ${WITH_LIB_${lib_upper}_EXAMPLES} ${CMAKE_MATCH_1})
endif()
endforeach()
message(STATUS "Glad examples: ${WITH_LIB_GLAD_EXAMPLES}")
message(STATUS "GLFW examples: ${WITH_LIB_GLFW_EXAMPLES}")
endmacro()
The problem is that ${WITH_LIB_${lib_upper}_EXAMPLES} is not available
anymore after the foreach, i was not able to find something in the docs
about this, i hope someone here can help me out.
best regrads!

Now i've two problem - the CMAKE_MATCH_0 contains the hole string and
not only the part the is in the (), i need only the part from the ()
- is there another command i can use for this ?
CMAKE_MATCH_1

[CMake] General question
Hi everyone,
i have the following code:
set(ALL_LIBS "glad;glfw")
# WITH_LIB_GLAD
option(WITH_LIB_GLAD 1)
option(WITH_LIB_GLAD_EXAMPLE_BASIC "Build the basic Glad example (default:0)" 1)
option(WITH_LIB_GLAD_EXAMPLE_SECOND "Build the second Glad example (default:0)"
1)
# WITH_LIB_GLFW
option(WITH_LIB_GLFW 1)
option(WITH_LIB_GLFW_EXAMPLE_CBASIC "Build the basic GLFW C example
(default:1)" 1)
option(WITH_LIB_GLFW_EXAMPLE_CPPBASIC "Build the basic GLFW C example
(default:1)" 1)
## bsBuildLib ##
macro(bsBuildLibs libs)
foreach(lib ${libs})
message(STATUS "Searching incude path for lib: <${lib}>")
bsIncludeLibs(${lib})
bsBuildLibExamples(${lib})
endforeach()
endmacro()
###
## bsIncludeLibs ##
###
macro(bsIncludeLibs lib)
message(STATUS "INCLUDE library ${lib}")
include("lib_${lib}")
endmacro()
## bsBuildLibExamples ##
macro(bsBuildLibExamples lib)
# get all examples
foreach(_var in VARIABLES)
string(TOUPPER ${lib} lib_upper)
if(_var MATCHES "WITH_LIB_${lib_upper}_EXAMPLE_([A-Za-z]+)")
message(STATUS "Found example: ${CMAKE_MATCH_0}")
endif()
endforeach()
endmacro()
The final result should be that i get the name of the examples, like for
glad BASIC and SECOND and for glfw CBASIC and CPPBASIC.
best regards!

[CMake] general question on documenting modules using the new FooConfig.cmake files
Hi, I've got a general question. Regular cmake FindFoo.cmake modules are documented by putting the docs at the top of the file. This documentation should list the variables, macros etc. provided by that module. Now if I switch to using FooConfig.cmake files and just very simple FindFoo.cmake files (basically only for getting some nicer messages etc.), how do I do this then ? I still could put the documentation in the FindFoo.cmake file, but this documentation would be for stuff which is in the FooConfig.cmake file, which is loaded later. While this is no technical problem, there is the real problem that the contents of the FooConfig.cmake file can change, i.e. a new variable can be added. But this doesn't necessarily mean that also the FindFoo.cmake changes. But if it doesn't, then the documentation is out of date. So, what would you prefer where to put the documentation ? In the FooConfig.cmake file, which is relatively hidden ? Or in the FindFoo.cmake file, which can get out of sync to the contents of the FooConfig.cmake file ?
