Difficulty Compiling c2ffi on FreeBSD 12 and Debian 10 - cmake

I am having problems installing c2ffi (https://github.com/rpav/c2ffi) on both FreeBSD 12 and Debian 10. I need c2ffi in order to use some Common Lisp bindings that rely on c2ffi.
On FreeBSD 12, I have both Clang 6.0 (default) and 10.0 installed; c2ffi requires LLVM 10.0. Because cc and c++ refer to Clang 6.0 in my FreeBSD installation, I set PATH to /usr/local/llvm10/bin:$PATH, and I also set aliases to refer to clang and clang++. I have cmake version 3.17.3 installed. However, when I make it to the make phase of installing c2ffi, I run into the following error:

The file libclang-cpp.so is present in my /usr/local/llvm10/lib directory, but cmake does not detect it. I tried various other approaches, including setting the LD_LIBRARY_PATH and CMAKE_LIBRARY_PATH environment variables, but to no avail; I received the same error message as above.
I gave up installing c2ffi on FreeBSD and tried installing it on a fresh install of Debian 10 with LLVM 10.0 and cmake 3.18.1. However, when I ran make on Debian, I ended up with the following error message:
[ 7%] Building CXX object CMakeFiles/c2ffi.dir/src/AST.cpp.o

make: *** [Makefile:149: all] Error 2
I am wondering how I can build c2ffi on my FreeBSD and Debian systems?

On my FreeBSD installation, in the CMakeLists.txt I replaced the line
target_link_libraries(c2ffi PUBLIC clang-cpp LLVM)
with
target_link_libraries(c2ffi PUBLIC /usr/local/llvm10/lib/libclang-cpp.so LLVM)
On my Debian installation, it turned out that I did not have one of the libclang development packages installed. After installing that package I was able to run make without any problems.

The project's CMakeLists.txt is broken, so bug upstream. Actualy, there are numerous pull requests already filed:
https://github.com/rpav/c2ffi/pull/70
https://github.com/rpav/c2ffi/pull/68/
https://github.com/rpav/c2ffi/pull/65/
You can try these, or combine them into a working solution.

I am stuck. Don't know what to try to solve this issue.
I did not find anything anywhere ...
Working on it for most of 2 days, I did find this site that presents a working method of building libx265 stuff on Apple Silicon and works for me on macOS 13.0.1. https://www.osxexperts.net/ Problem is, it only builds the libraries for building it into ffmpeg, no executable binary.
When I tried to get the executable also, by removing -DENABLE_CLI=OFF from the last cmake command, the error comes back. Put it back in, everything completes without error.
Here is the full process that works for me (no executable). It builds a multilibrary that can encode 8, 10, or 12-bit video:
cd x265/source
#### 12 bit
cmake -DCMAKE_INSTALL_PREFIX:PATH=${TARGET} -DHIGH_BIT_DEPTH=ON -DMAIN12=ON -DENABLE_SHARED=NO -DEXPORT_C_API=NO -DENABLE_CLI=OFF .
make
mv libx265.a libx265_main12.a
make clean-generated
rm CMakeCache.txt
#### 10bit
cmake -DCMAKE_INSTALL_PREFIX:PATH=${TARGET} -DHIGH_BIT_DEPTH=ON -DMAIN10=ON -DENABLE_SHARED=NO -DEXPORT_C_API=NO -DENABLE_CLI=OFF .
make clean
make
mv libx265.a libx265_main10.a
make clean-generated && rm CMakeCache.txt
#### 8 bit and all together
# removed -DENABLE_CLI=OFF from last one so we get the x265 binary
cmake -DCMAKE_INSTALL_PREFIX:PATH=${TARGET} -DEXTRA_LIB="x265_main10.a;x265_main12.a" -DEXTRA_LINK_FLAGS=-L. -DLINKED_10BIT=ON -DLINKED_12BIT=ON -DENABLE_SHARED=OFF -DENABLE_CLI=OFF .
make clean
make
mv libx265.a libx265_main.a
# this is Apple's libtool
libtool -static -o libx265.a libx265_main.a libx265_main10.a libx265_main12.a
make install
When I remove the last -DENABLE_CLI=OFF, here's the error:

EDIT: #Peter Betz, see the issue report. Until the developers correct this error, it will compile if you edit x265/source/common/aarch64/pixel-util.S, line 2410. Add an underscore as follows. Change:

I'm on MacOS Intel (i386-apple-darwin11.3.0)
Not sure where to go next, do I need to edit the CMakeList somehow?
Any help much appreciated
EDIT:
The cmake error log contains the following :
Compiling the C compiler identification source file "CMakeCCompilerId.c" failed. Compiler: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc Build flags: Id flags:

This is actually a bug in the CMakeList.txt because the library-list for the glm.so module does not contain the liblua.
If you apply the following patch
diff --git a/CMakeLists.txt b/CMakeLists.txt
index 8cf8a1a6..6eda2a17 100644
--- a/CMakeLists.txt
+++ b/CMakeLists.txt

IF( LUA_BUILD_AS_DLL )
TARGET_LINK_LIBRARIES(glm PUBLIC ${interpretor_target})
TARGET_COMPILE_DEFINITIONS(glm PRIVATE LUA_BUILD_AS_DLL)
to the freshly cloned repository and then do (inside the cloned repository):
git submodule update --init
mkdir build
cd build
cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Release -DONE_LUA=ON ..
make
you should find the files glm.so, lua and luac in your build directory. At least that worked on my Intel MacBook.
Using liblua_static in the CMakeList.txt for the library glm makes sure, that the resulting glm.so does not need the liblua dynamic library but contains the required code statically. That avoids problems when loading glm.so and the liblua library not being in the library path.
I opened an issue in the GitHub repository for it. So hopefully it will get fixed for everybody soon.
Usually it'll be something like -lYourLibrary not found, if -lSystem for example is not found, try adding it to your CMakeLists.
Are you still having the issue?

make: have built target; make install : *** No rule to make target 'install'

In Ubuntu20.04.
I want to insatll easy3d, but I can not make install it successfully.
make

And the build have files:
CMakeCache.txt CMakeFiles Makefile cmake_install.cmake libeasy3d.a
Then I excute the command make install, I got
make: *** No rule to make target 'install'. Stop.
How could I fix it
I made a big mistake that is nothing to install.

Conan and Raspberry Pico, how to use together?

Good morning!
I'm rewriting this question because, after a lot of reading and try-fails, I go further on that but I get staked again.
What I'm trying to accomplice here is: Use Conan as a Package manager for the embedded device "Raspberry PICO" from my Mac (with CLion)
The change from the previous question is that now I'm creating a package and I do not use only the "standalone" packages manager.
This "package" is on github.com. To install and try to compile it, you will need also the Pico SDK.
Some facts:
The new c++ project without Conan but with SDK is compiling and working on an embedded device.
The Conan project without Pico SDK is compiling correctly.
I really tried every possible configuration on the profile file and there are two mainly configuration profiles that brings to two different errors during build:
The first one is without any environments. This is because on CLion I'm not adding any environment and the project itself (without conan, but oblivious with SDK for pico) is builder correctly.

ERROR: conanfile.py (blink/0.1): Error in build() method, line 39
cmake.configure()
ConanException: Error 1 while executing cmake -G "Unix Makefiles" -DCMAKE_TOOLCHAIN_FILE="/Users/jure.prah/CLionProjects/rpi-pico/conan-blink-mosfet/build/generators/conan_toolchain.cmake" -DCMAKE_INSTALL_PREFIX="/Users/jure.prah/CLionProjects/rpi-pico/conan-blink-mosfet/package" "/Users/jure.prah/CLionProjects/rpi-pico/conan-blink-mosfet/src"
Also here I did all the variants and tests, but everything leads to this error. Besides, I checked the toolchain paths and there are correct.
I'm completely lost now. :(

Compiling on Beagleboard - Fail on AR

I am Compiling on a Beagleboard-Xm, Kernel:
root#beagleboard:~# uname -a
Linux beagleboard 2.6.32 #3 PREEMPT Tue Jul 26 10:56:56 CEST 2011 armv7l unknown
I now try to compile a static library with CMake, and everything is working fine, until it comes to linking of the library:
root#beagleboard:/usr/src/build/beaglebuild# make

In my the "ar --help" prints the same stuff.
Is there a way to get linking running on the board?
What may be the Issue?
Some other System Versions:
root#beagleboard:~# cmake --version
cmake version 2.8.2

After much trouble I cross-compiled a fully up-to-date version of ar (i thing the one on the board was outdated) and I got rid of BusyBox.
Now everything works as I expected.
