Broken CMake configuration

[akallabeth]

Describe the bug

CMake is not able to install libcbor due to a bug in the configuration

To Reproduce

1. cmake -GNinja -Bxxx -S. -DCMAKE_INSTALL_PREFIX=/tmp/cbor
2. cmake --build xxx/ --target install
3. watch the install step failing

Expected behavior

A properly installed libcbor under /tmp/cbor/

Environment

current master
all os tested so far (mac os 14, debian 12, windows 10)

This is not actionable. Can you please provide the exact environment description and logs?

@PJK ok, figured out what was going on.

libcbor/CMakeLists.txt

Line 11 in 9b1b5a1

option(CMAKE_SKIP_INSTALL_ALL_DEPENDENCY "cmake --build --target install does not depend on cmake --build" true)

is what causes this.
reading through https://cmake.org/cmake/help/latest/variable/CMAKE_SKIP_INSTALL_ALL_DEPENDENCY.html tells me that is what you desired with that change?

so, to sum up:
with CMAKE_SKIP_INSTALL_ALL_DEPENDENCY=ON you need to run:

1. cmake -GNinja -Bxxx -S. -DCMAKE_INSTALL_PREFIX=/tmp/cbor
2. cmake --build xxx
3. cmake --install xxx or cmake --build xxx --target install

whereas with

1. cmake -GNinja -Bxxx -S. -DCMAKE_INSTALL_PREFIX=/tmp/cbor -DCMAKE_SKIP_INSTALL_ALL_DEPENDENCY=OFF
2. cmake --build xxx --target install

suffices.
