Description
Hey,
I just upgraded to 0.12 and found this error in my CMake projects (rsb included through pkg-config: PKG_CHECK_MODULES(LIBS REQUIRED opencv rsc0.12 rsb0.12 rst0.12 ...) ).
Changing some names to RST_EXPORT makes these errors disappear. It seems like the CXX_FLAGS contain RST_EXPORT somehow.

Btw: I just switched to the CMake-Version of finding libraries and it works fine.

I can't see how this should happen. In any case, pkg-config or cmake, you need to export the cflags provided by the dependency mechanism. Both should export RSTSTABLE_EXPORT correctly. Otherwise something is messed up in the installation. On master and csra master the CMakeLists.txt defines:
IF(WIN32)
SET(RST_CFLAGS "/DRSTSTABLE_EXPORT=__declspec(dllimport)")
SET(RSTSANDBOX_CFLAGS "/DRSTSANDBOX_EXPORT=__declspec(dllimport)")
SET(RSTDEPRECATED_CFLAGS "/DRSTDEPRECATED_EXPORT=__declspec(dllimport)")
ELSE()
SET(RST_CFLAGS "-DRSTSTABLE_EXPORT=")
SET(RSTSANDBOX_CFLAGS "-DRSTSANDBOX_EXPORT=")
SET(RSTDEPRECATED_CFLAGS "-DRSTDEPRECATED_EXPORT=")
ENDIF()
and the respective pkg-config file is configured from:
Cflags: -I${includedir}/@INSTALL_PREFIX@/stable @RST_CFLAGS@
So either you grabbed an old version of a pkg-config file from ancient times or something is weird. Please show the Cflags provided by pkg-config for you.

Okay it seems like the way cmake handles pkg-config files is kind of broken, giving semicolon-separated lists for Cflags. Switching to CMake is a better solution.
