If you don't set `GPU_TARGETS` on the cmake command line, CK is built for all GPU targets
supported by the current compiler (this may take a long time).
supported by the current compiler (this may take a long time).
NOTE: If you try setting `GPU_TARGETS` to a list of architectures, the build will only work if the
architectures are similar, e.g., `gfx908;gfx90a`, or `gfx1100;gfx1101;gfx11012`. Otherwise, if you
want to build the library for a list of different architectures,
you should use the `GPU_ARCHS` build argument, for example `GPU_ARCHS=gfx908;gfx1030;gfx1100;gfx942`.

Additional cmake flags can be used to significantly speed-up the build:
* `INSTANCES_ONLY` (default is OFF) must be set to ON in order to build only the instances and library
while skipping all tests, examples, and profiler. This is useful in cases when you plan to use CK as a
dependency and don't plan to run any examples or tests.
* `DTYPES` (default is not set) can be set to any subset of "fp64;fp32;fp16;fp8;bf16;int8" to build
instances of select data types only. The main default data types are fp32 and fp16; you can safely skip
other data types.
