Box64 Cross-compiling: Can I specify where the library files are going?

[SoftwareGuy]

I'm trying to do some cross-compiles on my devices to target specific ARM64 devices, and I'm having difficulty getting the libraries that Box64 compiles to go into a specific folder. The following is my command line (note the slashes are just to escape the newline):

cmake -D CMAKE_C_COMPILER=aarch64-linux-gnu-gcc -D CMAKE_CXX_COMPILER=aarch64-linux-gnu-g++ \ 
-D CMAKE_INSTALL_PREFIX=$(pwd)/box64-rpi -D ARM_DYNAREC=ON -D CMAKE_BUILD_TYPE=RelWithDebInfo \ 
-D RPI3ARM64=1

I'll break it down step by step:

• I'm using a x64 host, so I'm using a cross compiler toolchain.
• I want the compiled files to be placed in the CMAKE_INSTALL_PREFIX path, which evaluates to /workdir/box64-rpi.
• I'm building a release binary with debug info.
• I'm wanting to use the R-Pi 3 enhancements where possible.

However, with this I find that the box64 binary is copied into /workdir/box64-rpi/bin but other stuff gets placed in /etc and /usr/lib. I want it to be placed in /workdir/box64-rpi/etc and /workdir/box64-rpi/usr/lib.

What am I doing wrong?

that's probably issues with the cmake project. I need to check that out.

If it helps, I think CMake gives a hint that when I specify other GNUInstallDir parameters (ie CMAKE_INSTALL_LIBDIR) that they aren't used by the project.
