Using CMake to compile Assimp on Windows 10 - cmake

Question

I am attempting to use assimp for model importing in openGL. However, when building assimp 4.1.0, I get this:
15>-- Install configuration: "Debug"
15>CMake Error at cmake_install.cmake:36 (file):
15> file cannot create directory: C:/Program Files
15> (x86)/Assimp/lib/cmake/assimp-4.1. Maybe need administrative privileges.
I should have administrative privileges, but I am not entirely sure. If not, how would I update this. If this is not the case, what would another course of action be? My project and assimp both are under Debug as well as Win32 (this gave a prior error, so I changed that).
Thank you.

Answer 1

I'm trying another way which #Daniel Schepler said, install other places and then set the PATH to the prefix path in environment:
Example on my cmake and build and install: [in Window10]
# cmake
cmake -DCMAKE_INSTALL_PREFIX=D:\Users\installpkg\bin -S . -B build -G "MinGW Makefiles"
# build and install
cmake --build build --target install
Explain a little bit:
-DCMAKE_INSTALL_PREFIX=D:\Users\installpkg\bin This flag is set the install path to = path
-G "MinGW Makefiles" is for MinGW to make.
Then you will see the result [Like I'm installing the glog now]:
PS D:\Users\installpkg\glog> cmake --build build --target install
