My libraries aren't going to the specified directory in cmake

I'm creating a library, and it works fine, but I've specified the libraries to be created on the directory "${CMAKE_CURRENT_SOURCE_DIR}/Build/MSVC/bin" but is being created on the build folder with the name lib{ProyectName}.lib (it should not have the lib prefix) this is my CMakeLists:

cmake_minimum_required(VERSION 3.26)



add_definitions(-DUNICODE -D_UNICODE)

project(AxoSerial-MSVC)
set(CMAKE_CXX_STANDARD 17)
add_library(AxoSerial-MSVC STATIC ${CMAKE_CURRENT_SOURCE_DIR}/src/AxoSerial.cpp)
target_include_directories(AxoSerial-MSVC PUBLIC ${CMAKE_CURRENT_SOURCE_DIR}/include)
set_target_properties(AxoSerial-MSVC
        PROPERTIES
        RUNTIME_OUTPUT_DIRECTORY "${CMAKE_CURRENT_SOURCE_DIR}/Build/MSVC/bin"
        CMAKE_CXX_COMPILER "C:/Program Files/Microsoft Visual Studio/2022/Community/VC/Tools/MSVC/14.29.30133/bin/HostX64/x64/cl.exe"
        SUFFIX ".lib"
)

project(AxoSerial-MinGW)
set(CMAKE_CXX_STANDARD 17)
add_library(AxoSerial-MinGW STATIC ${CMAKE_CURRENT_SOURCE_DIR}/src/AxoSerial.cpp
        main.cpp)
target_include_directories(AxoSerial-MinGW PUBLIC ${CMAKE_CURRENT_SOURCE_DIR}/include)
set_target_properties(AxoSerial-MinGW
        PROPERTIES
        RUNTIME_OUTPUT_DIRECTORY "${CMAKE_CURRENT_SOURCE_DIR}/Build/MSVC/bin"
        CMAKE_CXX_COMPILER g++
        SUFFIX ".lib"

project(main)
set(CMAKE_CXX_STANDARD 17)
add_executable(main main.cpp)
target_link_libraries(main PRIVATE AxoSerial-MSVC)
target_include_directories(main PUBLIC ${CMAKE_SOURCE_DIR}/include)

As seen in the code, I've tried :

RUNTIME_OUTPUT_DIRECTORY "${CMAKE_CURRENT_SOURCE_DIR}/Build/MSVC/bin"

Solution

From your example, you're setting RUNTIME_OUTPUT_DIRECTORY hoping that your library will be dumped in it.

A quick check of CMake's documentation page on RUNTIME_OUTPUT_DIRECTORY shows us that the variable is used to specify a path whose role is "Output directory in which to build RUNTIME target files."

If you follow the link to RUNTIME, you'll stumble upon this definition:

A runtime output artifact of a buildsystem target may be:

The executable file (e.g. .exe) of an executable target created by the add_executable() command.

On DLL platforms: the executable file (e.g. .dll) of a shared library target created by the add_library() command with the SHARED option.

Knowing this, if you take a look at your example you'll notice that all your library targets were created as STATIC libraries instead of a SHARED library.

(...)


add_library(AxoSerial-MSVC STATIC ${CMAKE_CURRENT_SOURCE_DIR}/src/AxoSerial.cpp)

(...)

add_library(AxoSerial-MinGW STATIC ${CMAKE_CURRENT_SOURCE_DIR}/src/AxoSerial.cpp
        main.cpp)

(...)

Hope this helps.
