CLion support

[TaxMachine]

I'm trying to get it work as a CLion Toolchain but when I set the compiler like this

CMake: Bundled
Build Tool: Detected: Ninja
C Compiler: /home/taxmachine/msvc/bin/x86/cl
C++ Compiler: /home/taxmachine/msvc/bin/x86/cl
Debugger: Bundled GDB

I get this error "Test CMake run finished with errors"

-- The C compiler identification is MSVC 19.42.34435.0
-- The CXX compiler identification is MSVC 19.42.34435.0

Can you add some option to indicate that you're cross compiling for a Windows target, similar to -DCMAKE_SYSTEM=Windows on the command line? It looks like it tries to invoke the lib.exe command with Unix ar style options, so it somehow seems to not have picked up the fact that the tools should be invoked with MSVC style options, even if it did say The C compiler identification is MSVC 19.42.34435.0.

my CMakeLists looks like this

cmake_minimum_required(VERSION 3.30)
project(some_project)

set(CMAKE_GENERATOR_PLATFORM Win32)  # Force 32-bit compilation
set(CMAKE_SYSTEM_PROCESSOR x86)      # Specify x86 architecture
set(CMAKE_SYSTEM_NAME Windows)

set(CMAKE_CXX_STANDARD 23)
set(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} /MT")
set(CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS_RELEASE} /MTd")
file(GLOB_RECURSE SOURCES "src/**")


add_library(some_project SHARED ${SOURCES})

target_link_libraries(some_project PRIVATE "${CMAKE_SOURCE_DIR}\\libs\\detours.lib")

[mstorsjo]

I think some of these variables need to be set already at the time of the project() statement, either set on the command line or via a cmake toolchain file. Or what if you move the CMAKE_SYSTEM_NAME, CMAKE_SYSTEM_PROCESSOR and CMAKE_GENERATOR_PLATFORM options to the top of the file before project()?
