Description Alexander Trufanov 2017-02-24 23:27:08 UTC 
Have just got up-to-date version of Skanlite sources from Github page: 
https://github.com/KDE/skanlite
Then tried cmake CMakeLists.cmake && make all
And got following error messages:

[  9%] Automatic moc for target skanlite
[  9%] Built target skanlite_automoc
Scanning dependencies of target skanlite
[ 18%] Building CXX object src/CMakeFiles/skanlite.dir/main.cpp.o
In file included from /home/truf/dev/skanlite/src/main.cpp:33:0:
/home/truf/dev/skanlite/src/version.h:1:3: error: invalid preprocessing directive #This
 # This is a basic version file for the Config-mode of find_package().
...

It seems that CMakeLists.cmake contains error. Looks like skanlite generates version.h from version.h.cmake with help of configure_file().
But before that it calls ecm_setup_version() which overwrites version.h.cmake template with package version file. Then nothing works. I don't understand why package version file is created on top of version file and how it's supposed to be used.

To be able to build the sources I had to comment ecm_setup_version() invocation in CMakeLists.cmake before calling cmake first time.

It works if cmake is called from subfolder like:

mkdir build
cd build
cmake ..
make

And doesn't work if only executed from project's root folder.
