Cmake error: cannot specify include directories

[ralpha]

I got the error below while compiling: https://github.com/ragundo/DwarfExplorer
Reference: ragundo/DwarfExplorer#1

I got this error while compiling with cmake (v 3.10.2, Linux):

CMake Error at plugins/DwarfExplorer/dfhack-qt/CMakeLists.txt:4 (target_include_directories):
  Cannot specify include directories for imported target "dfhack-qt-common".

Was an error with the https://github.com/cvuchener/dfhack-qt/blob/58225d74672e1f870cc9b23c8a4c747900d7f3df/CMakeLists.txt file:

target_include_directories(dfhack-qt-common INTERFACE ${CMAKE_CURRENT_SOURCE_DIR}/include)

gave that error. But fixed it with some searching and changing it to this line:

set_property(TARGET dfhack-qt-common APPEND PROPERTY INTERFACE_INCLUDE_DIRECTORIES
  $<BUILD_INTERFACE:${CMAKE_CURRENT_SOURCE_DIR}/include>
  )

---

Also one small compile warning:

../plugins/DwarfExplorer/dfhack-qt/qapplication/LogFilterProxyModel.cpp:104:33: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
     if (ok && type >= 0 && type < accepted_types.size() && !accepted_types[type])
                            ~~~~~^~~~~~~~~~~~~~~~~~~~~~~

I'm always lost with cmake versions. I think this command requires cmake 3.11 (https://gitlab.kitware.com/cmake/cmake/-/commit/fe4b25ec2fa09a50b6ffbfcf29e118afdfba0659). But you already found the workaround.
