So far, we have not defined any custom compiler flags, but from the reference Autotools build, we remember that the code was compiled with -g -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=1 -O2 using the GNU C compiler.
Our first approach could be to define the following:
if(CMAKE_C_COMPILER_ID MATCHES GNU) set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -g -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=1 -O2")endif()
And, we would place this code on top of src/CMakeLists.txt, right before generating source files (since pathdef.c uses ${CMAKE_C_FLAGS}):
# <- we will define flags right hereinclude(autogenerate.cmake)generate_config_h()generate_pathdef_c()generate_osdef_h()
A slight improvement to the compiler flag definitions would be to define
