<div dir="ltr">Hi,<div><br></div><div>I'm having a project here where cmake refuses to recognize the "COMPONENT" option for the install() command for certain targets.</div><div><br></div><div>Within the project there are several subdirs, the top-level CMakeLists.txt has a component-install rule like this:</div>
<div><br></div><div>INSTALL(DIRECTORY ${PROJECT_BINARY_DIR}/doc/html DESTINATION share/doc/myapp COMPONENT documentation)<br></div><div><br></div><div>which generates the expected output in the cmake_install.cmake file. However several subdirectories contain executable targets for which the cmake_install.cmake file uses the "Unspecified" component. The executable target files look like this:</div>
<div><br></div><div><div>SET(SOURCES</div><div> main.cpp object.cpp)</div><div><br></div><div>SET(MOCABLES</div><div> object.h)</div><div><br></div><div>QT4_WRAP_CPP(MOC_SOURCES ${MOCABLES})</div><div><br></div>
<div>ADD_EXECUTABLE(myapp ${SOURCES} ${MOC_SOURCES})</div><div>TARGET_LINK_LIBRARIES(myapp ${QT_LIBRARIES})</div><div><br></div><div># Installation</div><div>INSTALL(TARGETS myapp RUNTIME DESTINATION bin</div><div> ARCHIVE DESTINATION lib</div>
<div> LIBRARY DESTINATION lib</div><div> COMPONENT applications)</div><div><br></div></div><div>I can't seem to find a reason for this misbehaviour using cmake --trace or cmake --debug-output. Are there any other ways (short of patching + compiling cmake) to find out what goes wrong here? And if not, can someone give me a hint where to start patching?</div>
<div><br></div><div>I'm using cmake 2.8.11.2 on Debian/GNU Linux.</div><div><br></div><div>In a very small example with just an executable target in a single cmake file everything works fine, but minimizing the real codebase is quite a bit harder than I thought.</div>
