## # ignition_modular_library
##
## Download and build a library from the Ignition Robotics project ( https://ignitionrobotics.org/ ).
##
## ## Usage:
## ```cmake
## ignition_modular_library(NAME <name>
##                          VERSION <version>
##                          SHA512 <sha512>
##                          [REF <ref>]
##                          [HEAD_REF <head_ref>]
##                          [PATCHES <patches>]
##                          [CMAKE_PACKAGE_NAME <cmake_package_name>]
##                          [DISABLE_PKGCONFIG_INSTALL])
## ```
##
## ## Parameters:
## ### NAME
## The name of the specific ignition library, i.e. `cmake` for `ignition-cmake0`, `math` for `ignition-math4`.
##
## ### VERSION
## The complete version number.
##
## ### SHA512
## The SHA512 hash that should match the downloaded  archive. This is forwarded to the `vcpkg_from_github` command.
##
## ### REF
## Reference to the tag of the desired release. This is forwarded to the `vcpkg_from_github` command.
## If not specified, defaults to `ignition-${NAME}${MAJOR_VERSION}_${VERSION}`.
##
## ### HEAD_REF
## Reference (tag) to the desired release. This is forwarded to the `vcpkg_from_github` command.
## If not specified, defaults to `ign-${NAME}${MAJOR_VERSION}`.
##
## ### PATCHES
## A list of patches to be applied to the extracted sources.
## This is forwarded to the `vcpkg_from_github` command.
##
## ### CMAKE_PACKAGE_NAME
## The name of the CMake package for the port.
## If not specified, defaults to `ignition-${NAME}${MAJOR_VERSION}`.
## 
## ### DISABLE_PKGCONFIG_INSTALL
## If present, disable installation of .pc pkg-config configuration files.
##
##
## ## Examples:
##
## * [ignition-cmake0](https://github.com/Microsoft/vcpkg/blob/master/ports/ignition-cmake0/portfile.cmake)
## * [ignition-math4](https://github.com/Microsoft/vcpkg/blob/master/ports/ignition-math4/portfile.cmake)
## * [ignition-fuel-tools1](https://github.com/Microsoft/vcpkg/blob/master/ports/ignition-fuel-tools1/portfile.cmake)
