Dear All,
I am building an application using cmake with external shared library
libLLAPI.so on Ububtu .
I am getting following error:
make -f Source/CMakeFiles/app.dir/build.make Source/CMakeFiles/app.dir/build

Before this, while building a library libLLAPI.so I got error " fatal error:
libudev.h: No such file or directory" .
It worked fine after installing libudev-dev .
CmakeList.txt for app:
include_directories (../../../Lib/LLAPI/Include)
include_directories (../Include)
include_directories (../../LLAPI/Include)
include_directories (../../../Build/Cmake/LLAPI_TestApp/Build/Source)

QT4_WRAP_CPP(MOCSrcs ../Include/cansettings.h ../Include/Logfile.h
../Include/ssbGui.h)
add_library(LLAPI SHARED IMPORTED)
set_property(TARGET LLAPI PROPERTY IMPORTED_LOCATION
${CMAKE_BINARY_DIR}/../../LLAPI/build/Source/libLLAPI.so)
add_executable (app ${UISrcs} ${MOCSrcs} main.cpp cansettings.cpp Logfile.cpp
ssbGui.cpp)
target_link_libraries (app ${QT_LIBRARIES} LLAPI)
#target_link_libraries (app ${QT_LIBRARIES} Qt4::QtGui Qt4::QtXml LLAPI)
install (TARGETS app RUNTIME DESTINATION ${PROJECT_BINARY_DIR}/lib)
Searched on Internet for solution but could not fix it.
Please guide .
Regards,
Nikita
