This folder was created as follows:
(1)
curl -L -O https://github.com/google/etc2comp/archive/9cd0f9c.zip
unzip 9cd0f9c.zip
mv etc2comp-* etc2comp
(2)
Remove the outer IF block and the EtcTool line from CMakeLists.txt
(3)
Add this line to EtcLib/CMakeLists.txt:
target_include_directories(EtcLib PUBLIC Etc EtcCodec)
The above line exposes the public header to downstream projects; it's the "Modern CMake"
alternative to the existing lines:
include_directories(./Etc)
include_directories(./EtcCodec)
See:

Add the following to the top of EtcBlock4x4Encoding_RGB8.cpp to prevent potential unbounded upper
loops due to reliance on undefined nan behavior.
#if defined(__clang__)
// Workaround for relying on undefined behavior (casting nan to unsigned int) which can cause hang
// behavior when the resulting int is used as a loop upper bound. Ideally this pragma would go in
// EtcConfig.h, but moving it there triggers asserts.
#pragma float_control(precise, off)
#endif
