Hello,
For the simple case of three directories and two projects - /root,
/root/p1, and /root/p2 - I would like to set some common flags for both
projects and then other flags should be independent. For instance, p1
should be compiled with "-std=c99 -Os" and p2 should be compiled with
"-std=c99 -O1". The first flag, -std=c99, is common to all projects and
the second, -Os, might be changed from project to project. How do I do this?
I thought I could create MyRulesOverride.cmake with the content:
set(CMAKE_C_FLAGS_INIT "-std=c99")
And that would be the end of it, but apparently not. The CMakeLists.txt
files in each project have a line such as " set(CMAKE_C_FLAGS "-Os")"
which is apparently overwriting the cached value from
CMakeCInformation.cmake. I can't write a line like "set(CMAKE_C_FLAGS
"${CMAKE_C_FLAGS} -Os")" because then the result is "-std=c99 -std=c99
-Os" for the second project.
Any help would be greatly appreciated.
David
