CMake Error at Jucer2CMake/CMakeLists.txt:22 (message): JUCE_ROOT must be defined about frut

[McMartin]

Hi @rdv00,

Thanks a lot for using FRUT and opening this issue.

The "Getting Started" instructions (https://github.com/McMartin/FRUT#getting-started) show how to build FRUT using CMake on the command line:

cmake .. -DCMAKE_INSTALL_PREFIX="../prefix" -DJUCE_ROOT="../../JUCE"

I guess you're using the CMake GUI, but JUCE_ROOT doesn't appear, since it is not a cache variable. I almost never use the CMake GUI, but I'm pretty sure you should be able to define arbitrary variables, including JUCE_ROOT.

I hope this helps!
