Hi all,
I'm using QNX and cmake works fine under it, except for one thing. By
default compilation under QNX looks like cross-compilation even if you work
using x86 platform and compiling for x86 platform too.
By default gcc does not has /usr/include directory as default directory for
headers, instead it has /usr/qnx650/target/x86/usr/include directory by
default for system related stuff. Many additional packages are directly
installed to /usr directory and have their headers respectively at /usr/
include.
When I tried to compile fluidsynth it has found libreadline at /usr/include/,
but excluded this directory when it was added directly through
include_directories("/usr/include"). Later I've tried to pass option
CMAKE_REQUIRED_INCLUDES to cmake, but it excludes /usr/include too.
I can see that UnixPaths.cmake module has following lines:
list(APPEND CMAKE_C_IMPLICIT_INCLUDE_DIRECTORIES
/usr/include
)
list(APPEND CMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES
/usr/include
)
but it seems that this is used only when using macro like
check_include_file() or find_library(), but not for compilation.
How I can add /usr/include to the list of header directories for
compilation?
Thanks in advance!
