Build error on Android

Here is the log
install-arm64-android-dbg-out.log

It seems caused by these lines

glm/glm/detail/setup.hpp

Lines 299 to 311 in 33b0eb9

In the install logs you are compiling with -Weverything. Is this intentional?

Ah, -Weverything was moved into the main CMakeLists and a variety of pragma clang diagnostic's were added in source to compensate. Now, the CMakeLists expects an explicit standard flag to be enabled so it can disable the c++98-compat checks.

Don't think the documentation has been updated to reflect this (ergonomics? i.e., should -Weverything be enabled by default outside of the CI).

In the install logs you are compiling with -Weverything. Is this intentional?

No, I just specify following options.

-DGLM_BUILD_LIBRARY=ON
-DGLM_BUILD_TESTS=OFF
-DGLM_BUILD_INSTALL=ON

Should I pass GLM_ENABLE_CXX_xxxxx ?

[christophe-lunarg]

-Weverything includes -Wc++98-compat. If you don't want to get these warnings, you can build with -Weverything and -Wnoc++98-compat.

No need to pass GLM_ENABLE_CXX_xxxxx.
