CMake can't find HPXCacheVariables.cmake

[karlfroldan]

Expected Behavior

CMake should be able to find HPXCacheVariables.cmake as listed in HPXConfig.cmake.

Actual Behavior

Error during generating Makefile with cmake with the following message:

Executing command: /usr/local/bin/cmake --no-warn-unused-cli -DCMAKE_TOOLCHAIN_FILE=/home/karl/.local/vcpkg/scripts/buildsystems/vcpkg.cmake -DCMAKE_EXPORT_COMPILE_COMMANDS:BOOL=TRUE -DCMAKE_BUILD_TYPE:STRING=Debug -DCMAKE_C_COMPILER:FILEPATH=/bin/clang-12 -DCMAKE_CXX_COMPILER:FILEPATH=/bin/clang++-12 -H/home/karl/dev/cpp/hpx -B/home/karl/dev/cpp/hpx/build -G "Unix Makefiles"
CMake Error at /home/karl/.local/vcpkg/installed/x64-linux/share/hpx/HPXConfig.cmake:13 (include):

   Unknown arguments specified

   /home/karl/.local/vcpkg/scripts/buildsystems/vcpkg.cmake:793 (_find_package)
   CMakeLists.txt:10 (find_package)

Furthermore, HPXCacheVariables.cmake is not located in /path/to/vcpkg/installed/x64-linux/share/hpx which I believe is the root of the problem.

Steps to Reproduce the Problem

Installed HPX Using VCPKG and created a blank C++ project with a blank Main.cpp and a CMakeLists.txt containing

cmake_minimum_required(VERSION 3.17.0)

project(HPXTUT)

find_package(HPX CONFIG REQUIRED)

Run with cmake -DCMAKE_TOOLCHAIN_FILE=/path/to/vcpkg/toolchain ..

Specifications

... Please describe your environment

• HPX Version: 1.7.1 (vcpkg version as of February 10, 2022)
• Platform (compiler, OS): clang++-12, Ubuntu 20.04 (WSL)
• Cmake version: 3.21.0

@karlfroldan thanks for reporting! We'll have a look as quickly as possible.

@karlfroldan Thanks for the notice! Seems like a bug and we will take actions to fix it ASAP. For the moment could you please try deleting #L96 from this file: <path_to_vcpkg>/vcpkg/ports/hpx/portfile.cmake ?

The line is: file(REMOVE "${CURRENT_PACKAGES_DIR}/share/hpx/HPXCacheVariables.cmake").

You will need to remove HPX and reinstall it with vcpkg after that. Please tell us how it went.

@gonidelis Hi, this resolved the issue and CMake generated the Makefile correctly. Thank you!

@gonidelis Hi, this resolved the issue and CMake generated the Makefile correctly. Thank you!

FWIW, we're working on getting this resolved here: microsoft/vcpkg#23042

[autoantwort]

The file was removed because it contained absolute paths and absolute paths are forbidden because ports must be relocatable because of binary caching. The following absolute paths are in the file:

set(HPX_BINARY_DIR C:/Users/LeanderSchulten/git_projects/vcpkg/buildtrees/hpx/x64-windows-rel)
set(HPX_SOURCE_DIR C:/Users/LeanderSchulten/git_projects/vcpkg/buildtrees/hpx/src/1.7.1-1f0e7f19f4.clean)

[hkaiser]

This issue has been resolved. The fix will be merged to the vcpkg repository (see microsoft/vcpkg#23042).
