Issues with Cmake (Linux Mint 20.3)

[mxrgann]

So I happen to have problems with building the repository, as when I use the "cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_INSTALL_LIBDIR=lib -DBUILD_TESTING=OFF .." command, it outputs the error below, not allowing me to install the theme:

CMake Error at CMakeLists.txt:12 (find_package):
Could not find a configuration file for package "ECM" that is compatible
with requested version "5.78.0".

The following configuration files were considered but not accepted:

/usr/share/ECM/cmake/ECMConfig.cmake, version: 5.68.0

-- Configuring incomplete, errors occurred!
See also "/home/morgan/Downloads/Lightly/build/CMakeFiles/CMakeOutput.log".

Any help will be much appreciated :)
