Build on macos Catalina, fails with meson.build:243:7: ERROR: Arrays do not have a method called 'found'.
I am building libnice with the meson builddir command, and have had errors with libffi and libssl. I ran the subproject wrap command for libffi as advised, and exported compiler flags for libssl.
libssl was then found by meson, but i can see in the meson.build file that if both libcrypto_dep and libssl_dep are found then it sets crypto_dep to an array.
Line 243 of the meson.build file and next block are error checking that either GnuTLS or OpenSSL are available, but it fails as crypto_dep is an array.
I just commented out the error block as i don't know enough about meson to fix this, but i thought i'd write this up in case it helps.
