CMake Error: The following variables are used in this project, but they are set to NOTFOUND.

Hi, I got the following error when compiling on Linux:

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
CPPUNIT_INCLUDE_DIR
used as include directory in directory ~/plast/plast-library/test/unit
CPPUNIT_LIBRARY
linked by target "PlastLibraryTest" in directory ~/plast/plast-library/test/unit

-- Configuring incomplete, errors occurred!

Hi,
you are probably missing "development files" for cppunit. On a Debian-based system (such as *buntu), you can install them by:

 sudo apt install libcppunit-dev

Another option (no extra installations), is to disable the unit testing by commenting lines 98--99 in the file plast-library/CMakeLists.txt, and then build.
