Appending to CMAKE_C_FLAGS

Question

I\'m using CMake for a project that comes in two versions, one of which requires -lglapi and the other does not.

So far the lines we used look like that:

Answer 1

Try to do this instead:

if(SINGLE_MODE)
    SET(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -lglapi")
    SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -lglapi")
endif(SINGLE_MODE)

Then, you are sure you append -lglapi to the existing ${CMAKE_CXX_FLAGS} string. Else, looks like something like a CMake list is being created.
