CPM.cmake Install Fails Build with "-Og: not found"

[xanderdunn]

Ubuntu 18.04
GCC 10.3.0
cmake 3.20.1
CPM.cmake 0.32.2

I installed CPM.cmake with:

mkdir -p cmake
wget -O cmake/CPM.cmake https://github.com/cpm-cmake/CPM.cmake/releases/latest/download/get_cpm.cmake

I added matplotplusplus to my CMakeLists.txt with:

include(cmake/CPM.cmake)
CPMAddPackage(
    NAME matplotplusplus
    GITHUB_REPOSITORY alandefreitas/matplotplusplus
    GIT_TAG origin/master # or whatever tag you want
)
option(CPM_USE_LOCAL_PACKAGES "Try `find_package` before downloading dependencies" ON)

Now, when I attempt to build my project I get:

Where is the -Og flag coming from, and how might I fix this build? I see it listed here as optimizing for the debug experience. Was it possibly removed in a more recent version of GCC?

[xanderdunn]

Note that I did not see this error when I copied the 1.1.0 source and built with this:

mkdir build
cd build
cmake ..
make -j 12
make install

Same GCC version: 10.3.0.

Does

include(cmake/CPM.cmake)
CPMAddPackage(
    NAME matplotplusplus
    GITHUB_REPOSITORY alandefreitas/matplotplusplus
    GIT_TAG v1.1.0
)
option(CPM_USE_LOCAL_PACKAGES "Try `find_package` before downloading dependencies" ON)

work?

There might be something wrong with this function.

[xanderdunn]

Thanks for the help. It looks like the change is to specify the v1.1.0 tag, correct? When I do that, I'm still seeing the same output:

I did notice this at the beginning of my cmake configuration:

-- CPM: adding package [email protected] (v1.1.0)
Setting CXX flags to default for Debug mode ( -D_GLIBCXX_USE_CXX11_ABI=1; -Og)

Which is from the set_optimization_flags macro you linked to, but I think the macro was introduced in v1.1.0

So I tried rolling back to v1.0.1 rather than the latest v1.1.0 . The build fails about half-way through with some unrelated compiler errors, but it no longer has the -Og problem:

-Og: not found is a weird error.

Setting it to "O0" here or to just nothing might solve the problem, but "-Og" should also work.
