CMake set target properties called with incorrect number of arguments

I'm trying to use OpenCV library in my project, but I get this error at runtime :

Build command failed.

CMake Error at CMakeLists.txt:13 (set_target_properties):

As commented, CMake uses the semicolon ; to define lists. So if the path contains semicolons, you must enclose the definition, and places where you use the variable pathToProject with double quotes:

set(pathToProject "C:\\Users\\Mouad;AITALI\\AndroidStudioProjects\\BGREMOVER")

...

set_target_properties(lib_opencv PROPERTIES IMPORTED_LOCATION "${pathToProject}/app/src/main/jniLibs/${ANDROID_ABI}/libopencv_java3.so")

The IMPORTED_LOCATION property only takes one value. So when you provide a list for that property, the set_target_properties() command cannot parse the arguments correctly, which yields the error.
