[CMake] How to set path to library header files?

[Chris Johnson]

I'm using Make as my build tool.  Here's the failing compile line with the
-I paths.  Indeed, they're not quite correct.  This is with the suggested
include_directories() directive.

[100%] Building CXX object prog/CMakeFiles/prog.dir/prog.cpp.o
cd /sandbox/src/.build/prog && /usr/bin/c++    -I/sandbox/include
-I/sandbox/src/src -I/sandbox/src/mylib    -o
CMakeFiles/prog.dir/prog.cpp.o -c /sandbox/src/prog/prog.cpp

Since the ../src/src path is wrong, I tried changing to
include_directories(${CMAKE_SOURCE_DIR}) and that seems to work.  That
seems to imply the top-level source is not part of the default include
path, correct?

Thanks,
..chris
