The way that cmake works is it provides the different FindXXX.cmake scripts for FindPackage directives. How the different Find-scripts look for different directories depend on the particular script in question. Each script comes with its own documentation that tells how you can configure the paths for finding that library.
There is a single CMAKE_MODULE_PATH directive that tells cmake where to look for the FindXXX.cmake scripts. Because emscripten is a cross-compiler, we have routed this directive to not look at any system cmake-provided paths, but instead we have a Modules path in emscripten repo where the Emscripten-specific find scripts can be put in. Currently we have only few of those, but pull requests that add more are welcome.
