I have downloaded an application from Github and following the instructions given there to 'build' my tool (https://github.com/abreheret/PixelAnnotationTool/tree/master/scripts_to_build).
Right now I'm trying to compile the application using steps given in that page,
cd .. mkdir x64 cd x64 cmake -DQT5_DIR=/path/to/Qt5.9.1/5.9.1/gcc_64/lib/cmake -G "Unix Makefiles" .. make
but I see the following error
CMake Error: The source directory "/opt" does not appear to contain CMakeLists.txt. Specify --help for usage, or press the help button on the CMake GUI.
What is going wrong? Ubuntu noob here, please help out! Thanks!
