I've come across an odd situation where I'm unsure what the most portable and recommended solution would be.I'm linking a program against the CURL and ICU libraries. CURL has traditional variables for the includes and libraries; ICU has imported targets. In FindICU: set_target_properties(${_ICU_imported_target} PROPERTIES INTERFACE_INCLUDE_DIRECTORIES "${ICU_INCLUDE_DIR}") In my code: find_package(CURL) find_package(ICU COMPONENTS uc data) [...] list(APPEND libxerces_c_DEPS ${CURL_LIBRARIES}) include_directories(${CURL_INCLUDE_DIRS}) list(APPEND libxerces_c_DEPS ICU::uc ICU::data) And the resulting includes on the compiler invocation: /usr/bin/CC -DHAVE_CONFIG_H -D_FILE_OFFSET_BITS=64 -I. -I/tmp/b2/xerces-source/src -Isrc -I/tmp/b2/xerces-source/tests -isystem /tmp/b2/superbuild-install/include -msse2 -MD -MT tests/CMakeFiles/XSValueTest.dir/src/XSValueTest/XSValueTest.cpp.o -MF tests/CMakeFiles/XSValueTest.dir/src/XSValueTest/XSValueTest.cpp.o.d -o tests/CMakeFiles/XSValueTest.dir/src/XSValueTest/XSValueTest.cpp.o -c /tmp/b2/xerces-source/tests/src/XSValueTest/XSValueTest.cpp The problem is this: CURL is in /usr/local/include ICU v55 is in /usr/local/include ICU v57 is in /tmp/b2/superbuild-install/include with its libs in /tmp/b2/superbuild-install/lib
Sorry, I noticed that the compiler invocation was from the wrong source file; it should have -I/usr/local/include right at the start, then -isystem /tmp/b2/superbuild-install/include at the end as above.
