Build error

[marco-trovato]

I remember Game Master and ArtMoney! The latter could even SAVE STATE in games that don't support saving! So THANK YOU for making this!

I am trying to build but i get the following error:

-- Checking for one of the modules 'jsoncpp'
CMake Error at /usr/share/cmake-3.25/Modules/FindPkgConfig.cmake:894 (message):
  None of the required 'jsoncpp' found
Call Stack (most recent call first):
  CMakeLists.txt:17 (pkg_search_module)


-- Checking for one of the modules 'icu-uc'
-- Could NOT find CxxTest (missing: CXXTEST_INCLUDE_DIR CXXTEST_PYTHON_TESTGEN_EXECUTABLE) 
-- Configuring incomplete, errors occurred!
See also "/home/debian/Documents/med/build/CMakeFiles/CMakeOutput.log".

(It's like cmake hates me and has an array of random errors for everything i try to compile.)

Could you care to spend few minutes to explain me what am i doing wrong? Maybe it can help other people in the future.
