The hard-coded path paths added to LIBRARY_PATH and CPLUS_INCLUDE_PATH
was not correct on Apple Silicon Macs, where homebrew installs into
/opt/homebrew/.
There's also no point in passing on the library location via compiler
environment variables, when we can use ODBC_ROOT. And we don't need
to pass it on as a CMake define, as a environment variable works just
fine. This decouples the provisioning of libiodbc from the build
configurations.
Pick-to: 6.9 6.8
