Trouble compiling on macos (Monterey 12.7.4)

[zpamaral]

Describe the bug
I had a hard time compiling libjxl. First, it failed because could not find “-lgmock”. Second, it failed because could not find the header files for highway.

To Reproduce
In addition to the OS mentioned, libjxl-0.10.2, my Clang is Apple clang version 14.0.0 (clang-1400.0.29.202); my gtest (gmock) is 1.14.0; my highway is 1.1.0; and my gcc is gcc (the real one) is 10.2.0 (do not think is relevant, but list it anyway).

Expected behavior
I expected the libraries and associated files to compile.

Solution
I was able to compile everything I wanted successfully, by doing the following:

1. Running:

./deps.sh

3. Running:

cmake -S . -B build -DJPEGXL_FORCE_SYSTEM_BROTLI=ON -DJPEGXL_FORCE_SYSTEM_LCMS2=ON -DJPEGXL_FORCE_SYSTEM_HWY=ON -DJPEGXL_ENABLE_DEVTOOLS=ON -DJPEGXL_TEST_TOOLS=OFF -DJPEGXL_ENABLE_JNI=OFF -DJPEGXL_ENABLE_JPEGLI=OFF -DJPEGXL_ENABLE_SKCMS=OFF -DJPEGXL_ENABLE_MANPAGES=OFF -DCMAKE_INSTALL_RPATH=/usr/local -DCMAKE_BUILD_TYPE=Release

4. Replacing the string “-lgmock” with the full path to the library:

find ./ -name link.txt -exec sed -i '.bak' 's/-lgmock//usr/local/lib/libgmock.a/g' {} ;

5. Adding a link to the directory hwy to the directory the contained the CMakeLists.txt (in this case libjxl-0.10.2)

ln -s third_party/highway/hwy hwy

6. After these steps, running:

cmake --build build

built everything without issues.

Environment

• OS: macos 12.7.4
• Compiler version: Apple clang-1400.0.29.202
• CPU type: x86_64
• cjxl/djxl version string: cjxl v0.10.2 [AVX2,SSE4,SSE2] (but irrelevant because post hoc)
