Hello
I am using Windows ansd Cmake 2.6. I am invoking CMake from command
window
which has set some environment variables. The environment
variables are
visible only the during the lifetime of the command window.
I am using the environment variables in many places through my
cmakelists.txt , for example in INCLUDE_DIRECTORIES, LINK_LIBRARIES
etc. The
environment variables are mainly set with file path strings.
Problem :
When I am working in Visual Studio on my project, if my
cmakelists.txt for
the project is changed, Cmake is rerun from Visual Studio.
Because Cmake is run from Visual Studio , and not the shell where the
environment variables are set , it can't recognize the environment
variables. How to overcome this ?
Thanks
Somewhere short after the PROJECT command, put something like this:
foreach(_var VAR1 VAR2 VAR3 VAR4)
if(NOT DEFINED ${_var})
set(${_var} "$ENV{${_var}}" CACHE INTERNAL "This is my super
variable ${_var}")
endif()
endforeach()
This will initialize internal cache variables with the values from the
environment, and then in subsequent runs use the values from the cache.
