A general-purpose CMake library that provides functions that improve the CMake experience following the best practices.

:
package_project
: automatic packaging/installation of the project
for seamless usage via find_package/target_link through CMake's

: automatic installation of vcpkg and the project

: automatic installation of conan and the project

project
and project_options
Here is an example of the usage:
cmake_minimum_required(VERSION 3.20)
# set a default CXX standard for the tools and targets that do not specify them.
# If commented, the latest supported standard for your compiler is automatically set.
# set(CMAKE_CXX_STANDARD 20)
include(FetchContent)
if(CMAKE_VERSION VERSION_GREATER_EQUAL "3.24.0")
cmake_policy(SET CMP0135 NEW)
endif()
# Add project_options from https://github.com/aminya/project_options
# Change the version in the following URL to update the package (watch the releases of the repository for future updates)
set(PROJECT_OPTIONS_VERSION "v0.36.1")
FetchContent_Declare(
_project_options

FetchContent_MakeAvailable(_project_options)
include(${_project_options_SOURCE_DIR}/Index.cmake)
# install vcpkg dependencies: - should be called before defining project()
run_vcpkg(

)
# Install conan dependencies: - should be called before defining project()

# Set the project name and language

# vcpkg test feature
if(FEATURE_TESTS)
list(APPEND VCPKG_MANIFEST_FEATURES "tests")
endif()
# Enable sanitizers and static analyzers when running the tests
if(FEATURE_TESTS)
set(ENABLE_CLANG_TIDY "ENABLE_CLANG_TIDY")

endif()
# Enable doxgen for the docs
if(FEATURE_DOCS)
set(ENABLE_DOXYGEN "ENABLE_DOXYGEN")
endif()
# Initialize project_options variable related to this project
# This overwrites `project_options` and sets `project_warnings`
# uncomment to enable the options. Some of them accept one or more inputs:

)
Then add the executables or libraries to the project:
add_executable(main main.cpp)
# link project_options/warnings
target_link_libraries(main
PRIVATE myproject_project_options myproject_project_warnings
)
# Find dependencies:
target_find_dependencies(main

# Link dependencies
target_link_system_libraries(main

)
# Package the project
package_project(TARGETS main)
add_library(my_lib "./src/my_lib/lib.cpp")
# link project_options/warnings
target_link_libraries(my_lib
PRIVATE myproject_project_options myproject_project_warnings
)
# Includes:

# Link dependencies:

# Package the project
package_project(
# Note that you must export `myproject_project_options` and `myproject_project_warnings` for `my_lib`
TARGETS my_lib myproject_project_options myproject_project_warnings
)
add_library(my_header_lib INTERFACE)
# link project_options/warnings
