Making a vcpkg package

[DimitrijeDobrota]

So I have a static/shared library that I've made using cmake-init and I am trying to include it in the other cmake-init project.

I am trying to run my own registry, but I am stuck with portfile.cmake.:

• Registry gets recognized
• Library gets downloaded
• Library gets built
• Content gets copied to ./build/dev/vcpkg_installed/x64-linux/
• When it comes to linking I get cemplate::cemplate target was not found.

The library in question is cemplate, and the portfile.cmake I currently have is:

vcpkg_from_git(
    OUT_SOURCE_PATH SOURCE_PATH
    URL git://git.dimitrijedobrota.com/cemplate.git
    REF fea2b26d496ab6250f966f7a216b9222be731559
    HEAD_REF master
)

set(name cemplate)

vcpkg_cmake_configure(
    SOURCE_PATH "${SOURCE_PATH}"
    OPTIONS
        "-D${name}_INSTALL_CMAKEDIR=share/${name}"
    OPTIONS_DEBUG
        "-D${name}_INSTALL_HEADERS=OFF"
)

# set(VCPKG_BUILD_TYPE release) # header-only

vcpkg_cmake_install()
vcpkg_cmake_install()
vcpkg_cmake_config_fixup(PACKAGE_NAME "${name}")
vcpkg_fixup_pkgconfig()
vcpkg_copy_pdbs()


configure_file(
    "${SOURCE_PATH}/LICENSE.md"
    "${CURRENT_PACKAGES_DIR}/share/${PORT}/copyright"
    COPYONLY
)

and vcpkg.json:

{
  "name": "cemplate",
  "version": "0.2.0",
  "description": "Simple C++ template engine",
  "homepage": "https://git.dimitrijedobrota.com/cemplate.git",
  "license": "MIT",
  "dependencies": [
    {
      "name": "vcpkg-cmake",
      "host": true
    },
    {
      "name": "vcpkg-cmake-config",
      "host": true
    }
  ]
}

Interesting thing to note is that when the link target is just cemplate, the configuration passes, but headers are not recognized.

I've been at it for hours, what am I missing?
Thanks in advance

You deleted the line that imports the export set in your CMake package: DimitrijeDobrota/cemplate@fea2b26#diff-a2af7ef15ed24fec1d5ad5cf93e0baf38c2d4ce41c3908c1e28febd24007013eR1

Just an fyi, but you call vcpkg_cmake_install twice in your port and call vcpkg_fixup_pkgconfig for a package that doesn't use .pc files.

Cheers mate, thanks a lot of the answer, that was the issue.

I have a question, why is this check necessary before doing the include if I have the dependency if(fmt_FOUND)? Also do I always have to list all of them here?

[friendlyanon]

The conditional makes sure that people who do find_package(dep) without REQUIRED get what they are supposed to. If dep's CMake package encounters a fatal error regardless of what the user requested, that's just be bad UX.

Makes sense, thanks a lot!
