[Buildroot] [PATCH 1/1] package/gtest: host-gtest install like a normal cmake package

[Paul Soucy]

host-gtest does not actually build and install gtest libraries or header files, it just installs the gmock_gen stuff. This patch will now build and install gtest to the host like a normal cmake package.

Thanks for your patch!

Could you give some details as to why you need gtest to be installed in
$(HOST_DIR) ?

Is this thing still needed? I applied your patch, and I was able to
successfully build the target gtest+gmock, even without gmock_gen being
installed in $(HOST_DIR)/bin/ by host-gtest.

Am I missing something?

Best regards,

Thomas

Hi Thomas,

Thanks for taking the time to look at the patch. The reason I would like
the option to install gtest to HOST_DIR is for running unit tests. Some of
our test suite needs to run on the HOST system. This patch solves the
problem.

I'm not sure if HOST_GTEST_POST_INSTALL_PYTHON thing is still needed. We do
not actually use the gmock feature of gtest. I was trying to preserve
existing functionality but not quite sure what the original intention of
this was.

Paul, All,

Sorry for the long delay...

On 2020-12-16 12:44 -0500, Paul Soucy spake thusly:

I rewrapped the commit log, and slightly extended it with the
information you rpovided elsewhere in the thread.

Applied to master with the above fixed, thanks.
