gmock/gtest not built/installed

### Describe the issue

compiling googletest natively on an RPi3 completes without errors.

The shared libraries build/install without problems, but no binaries are built/installed (/usr/local/bin/gmock /usr/local/bin/gtest).

How do I build gmock/gtest (or have I misunderstood).

### Steps to reproduce the problem

```
cmake -LAH -DCMAKE_C_FLAGS_RELEASE="-march=armv6zk -mtune=arm1176jzf-s -mfpu=vfp -Os -pipe -DNDEBUG" -DCMAKE_CXX_FLAGS_RELEASE="-march=armv6zk -mtune=arm1176jzf-s -mfpu=vfp -Os -pipe -DNDEBUG" -DCMAKE_INSTALL_PREFIX=/usr/local -DCMAKE_INSTALL_LIBDIR=/usr/local/lib -DCMAKE_BUILD_TYPE=Release -DCMAKE_VERBOSE_MAKEFILE=TRUE -DBUILD_SHARED_LIBS=ON -G Ninja ../
```

### What version of GoogleTest are you using?

googletest-1.15.2

### What operating system and version are you using?

piCore-15.x

### What compiler and version are you using?

gcc-13.2

### What build system are you using?

cmake/ninja

### Additional context

_No response_

Start with the CMake/Ninja configuration from the reproduction command and review which gmock/gtest targets are defined and installed. Clarify whether the expected binaries are part of the project’s supported install outputs, then document the correct build and installation behavior.
