Hi,
I have a small macro/function which I need often during buildsystem debugging:
function(PRINT_VARIABLES)
set(msg "")
foreach(var ${ARGN})
if(msg)
set(msg "${msg} ; ")
endif()
set(msg "${msg}${var}=\"${${var}}\"")
endforeach()
message(STATUS "${msg}")
endfunction()
it prints the values of the variables given as arguments.
Example:
print_variables(CMAKE_C_COMPILER
CMAKE_MAJOR_VERSION
THIS_ONE_DOES_NOT_EXIST)
Gives:
-- CMAKE_C_COMPILER="/usr/bin/gcc" ; CMAKE_MAJOR_VERSION="2" ;
THIS_ONE_DOES_NOT_EXIST=""
Ok to add to git ?
Or should this better be
message(VARIABLES CMAKE_C_COMPILER
CMAKE_MAJOR_VERSION
THIS_ONE_DOES_NOT_EXIST)
Or not at all ?
Then I'll put it in extra-cmake-modules, but it seems to generic that I think
it makes sense to have it in cmake directly.
Alex
