[CMake] Why are my static libs not being read?
The qt libraries are included in the target link flag (this project uses qt
of course), however the two lib files that exist in the lib folder in the
same directory are either not recognized. They draw up linker issues in the
compiler, even though I can tell through the cmake gui that it does find
those paths.
Any input at all would be great. Below I have included the CMakeLists.txt, a
screenshot of the cmake gui as well as a sample of the linking errors being
drawn.
PROJECT(CppSampleQt01)
FIND_PACKAGE(Qt4 REQUIRED)
//These are the lines I am concerned do not function appropriately. However
you can http://i.imgur.com/EDrHR.png see here that they are recognized by
CMake
FIND_LIBRARY(SIMPLONLIB lv.simplon lib)
FIND_LIBRARY(SIMPLONIMGPROC lv.simplon.imgproc lib)
SET(CppSampleQt01_SOURCES include/lv.simplon.class.cpp camera.cpp main.cpp
mainwindow.cpp osdep.cpp paint.cpp)
SET(CppSampleQt01_HEADERS include/lv.simplon.class.h camera.h mainwindow.h
osdep.h paint.h)
SET(CppSampleQt01_RESOURCES icons.qrc)
INCLUDE(${QT_USE_FILE})
ADD_DEFINITIONS(${QT_DEFINITIONS})
ADD_EXECUTABLE(CppSampleQt01 ${CppSampleQt01_SOURCES}
${CppSampleQt01_HEADERS_MOC}
${CppSampleQt01_RESOURCES_RCC})
TARGET_LINK_LIBRARIES(CppSampleQt01 ${QT_LIBRARIES})
INCLUDE_DIRECTORIES(${CMAKE_CURRENT_BINARY_DIR} include QExtSerialPort/src)
And here are some of the relevant linker errors that are drawn:
2lv.simplon.class.obj : error LNK2019: unresolved external symbol
__imp__LvEventKill@4 referenced in function public: unsigned int __thiscall
LvEvent::Kill(void) (?Kill@LvEvent@@QAEIXZ)
2lv.simplon.class.obj : error LNK2019: unresolved external symbol
__imp__LvEventFlush@4 referenced in function public: unsigned int
__thiscall LvEvent::Flush(void) (?Flush@LvEvent@@QAEIXZ)...

You need to add your 2 libraries in TARGET_LINK_LIBRARIES. CMake will
not do that automatically.

Re: [CMake] Why are my static libs not being read?
Include it using the flags? Like so:
TARGET_LINK_LIBRARIES(CppSampleQt01 ${QT_LIBRARIES} SIMPLONLIB
SIMPLONIMGPROC) ?
Because when I did this, the libs were not found either.

I think it should be:
TARGET_LINK_LIBRARIES(CppSampleQt01 ${QT_LIBRARIES} ${SIMPLONLIB}
${SIMPLONIMGPROC})
since both of these should be variables.

Re: [CMake] Why are my static libs not being read?
Thank you John, this did work. I get the idea now, thank you. I have another concern though, that I hope I can be helped with though it's doesn't fall under the original problem. So I am using a project within my project: http://i.imgur.com/bqqnp.png, and I found a custom https://qextserialport.googlegroups.com/attach/9b25d0e5e8974d99/CMakeLists.txt?view=1part=4 CMakeLists.txt for it created by the developers, and I was wondering how would I go about integrating that into my existing CMakeLists.txt, any input regarding how to go about doing this will be greatly appreciated. Thank you guys once again! -- View this message in context: http://cmake.3232098.n2.nabble.com/Why-are-my-static-libs-not-being-read-tp7581042p7581048.html Sent from the CMake mailing list archive at Nabble.com. -- Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://www.cmake.org/mailman/listinfo/cmake

Thank you guys once again! One way is to put this file along with the sources in a subdirectory of your project and use the add_subdirectory cmake command to add that to your project. Then add qextserialport to your TARGET_LINK_LIBRARIES. This time just use qextserialport since it is not a variable but a target. You will also have to add a entry to your include_directories for the location of the .h file in this subdirectory.
