How to add dependencies like Boost with CPMAddPackage?

[viniciusferrao]

Hello, this is a help call for anyone willing to help. I'm trying to add this template to an existing project but I'm having some issues with Boost and CLI11 dependencies.

I've changed the main CMakeLists.txt file with the following content:

# ---- Add dependencies via CPM ----
# see https://github.com/TheLartians/CPM.cmake for more info

#set(CPM_USE_LOCAL_PACKAGES ON)
include(cmake/CPM.cmake)

# PackageProject.cmake will be used to make our target installable
CPMAddPackage("gh:TheLartians/[email protected]")

CPMAddPackage(
  NAME Boost
  VERSION 1.82.0
  GITHUB_REPOSITORY "boostorg/boost"
  GIT_TAG "boost-1.82.0"
)

CPMAddPackage(
  NAME fmt
  GIT_TAG 10.0.0
  GITHUB_REPOSITORY fmtlib/fmt
  OPTIONS "FMT_INSTALL YES" # create an installable target
)

CPMAddPackage(
  NAME CLI11
  VERSION 2.3.2
  GITHUB_REPOSITORY CLIUtils/CLI11
  OPTIONS "CLI11_INSTALL YES"
)

CPMAddPackage(
  NAME spdlog
  VERSION 1.11.0
  GITHUB_REPOSITORY gabime/spdlog
  OPTIONS "SPDLOG_INSTALL YES"
)

CPMAddPackage(
  NAME magic_enum
  VERSION 0.9.3
  GITHUB_REPOSITORY Neargye/magic_enum
  OPTIONS "MAGIC_ENUM_OPT_INSTALL YES"
)

CPMAddPackage("gh:gsl-lite/[email protected]")

And added to target_link_libraries:

# Link dependencies
target_link_libraries(${PROJECT_NAME} PRIVATE fmt::fmt CLI11::CLI11 Boost::headers Boost::system Boost::thread spdlog::spdlog gsl::gsl-lite magic_enum::magic_enum resolv)

But when I try to configure with cmake -S all -B build I receive this error message:

-- Configuring done
CMake Error: install(EXPORT "CloysterHPCTargets" ...) includes target "CloysterHPC" which requires target "CLI11" that is not in any export set.
CMake Error: install(EXPORT "CloysterHPCTargets" ...) includes target "CloysterHPC" which requires target "boost_headers" that is not in any export set.
CMake Error: install(EXPORT "CloysterHPCTargets" ...) includes target "CloysterHPC" which requires target "boost_system" that is not in any export set.
CMake Error: install(EXPORT "CloysterHPCTargets" ...) includes target "CloysterHPC" which requires target "boost_thread" that is not in any export set.
-- Generating done
CMake Generate step failed.  Build files cannot be regenerated correctly.

I based the Boost settings from https://github.com/cpm-cmake/CPM.cmake (the snippets in README.md). Everything else I tried to figure out by myself.

Also I'm not sure if I done the changes in the right place, I don't get if I should add the required dependencies to the main CMakeLists.txt or if I should use the standalone directory and change CMakeLists.txt there. I didn't understand it's purpose correctly to be honest.

Thanks.

You have to install all your dependent packages!

[viniciusferrao]

You mean by setting the INSTALL option? I check for example the source code of CLI11 and found OPTIONS "CLI11_INSTALL YES", so I have enabled it on CPMAddPackage. Is that what you're referring to?

[ClausKlein]

Yes

[viniciusferrao]

Well something should be broken with the other projects, because that's what I've done and it's also on the CMakeLists.txt snipped that I showed. :(

What is about boost, it seems not to have an install rule?

You may also try to disable the EXCLUDE_FROM_ALL CPM.cmake option.
