I try to build libsnark on macOS High Sierra (Version 10.13) with:

cmake -DWITH_PROCPS=OFF ..

and I get the following error:

-- Configuring incomplete, errors occurred!

It seems that pkg-config can't find openssl. I tried to symlink the library as suggested here #86:

cd /usr/local/include
ln -s ../opt/openssl/include/openssl .

I searched and tried a lot how to make it work without any results. Any advice ?

Openssl info:

$ brew info openssl

A CA file has been bootstrapped using certificates from the SystemRoots
keychain. To add additional certificates (e.g. the certificates added in
the System keychain), place .pem files in
  /usr/local/etc/openssl/certs

and run
  /usr/local/opt/openssl/bin/c_rehash

This formula is keg-only, which means it was not symlinked into /usr/local,
because Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries.

If you need to have this software first in your PATH run:
  echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.zshrc

For compilers to find this software you may need to set:
    LDFLAGS:  -L/usr/local/opt/openssl/lib
    CPPFLAGS: -I/usr/local/opt/openssl/include
For pkg-config to find this software you may need to set:
    PKG_CONFIG_PATH: /usr/local/opt/openssl/lib/pkgconfig

Thanks in advanced.

EDIT

I also had to install pkg-config:

brew install pkg-config

It would be nice to be added as instruction under Building on Mac OS X section

I had the same issue, I did manage to get it working with:

LD_LIBRARY_PATH=/usr/local/opt/openssl/lib:"${LD_LIBRARY_PATH}"                    
CPATH=/usr/local/opt/openssl/include:"${CPATH}"                                    
PKG_CONFIG_PATH=/usr/local/opt/openssl/lib/pkgconfig:"${PKG_CONFIG_PATH}"          
export LD_LIBRARY_PATH CPATH PKG_CONFIG_PATH       

CPPFLAGS=-I/usr/local/opt/openssl/include LDFLAGS=-L/usr/local/opt/openssl/lib PKG_CONFIG_PATH=/usr/local/opt/openssl/lib/pkgconfig cmake -DWITH_PROCPS=OFF -DWITH_SUPERCOP=OFF ..

In travis-ci macOS Build Environment, for osx_image: xcode11, the path /usr/local/opt/openssl is somehow not linked correctly.

We could use brew --prefix openssl to find the correct path.

Or try this:

CPPFLAGS=-I$(brew --prefix openssl)/include LDFLAGS=-L$(brew --prefix openssl)/lib PKG_CONFIG_PATH=$(brew --prefix openssl)/lib/pkgconfig cmake -DWITH_PROCPS=OFF -DWITH_SUPERCOP=OFF ..

In the recent version of macOS Monterey and a brew version 3.6.3, this command results in the following error:

-- GMP: /opt/homebrew/lib/libgmp.dylib, /opt/homebrew/include
CMake Error at /opt/homebrew/Cellar/cmake/3.24.2/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:230 (message):
  Could NOT find OpenSSL, try to set the path to OpenSSL root folder in the
  system variable OPENSSL_ROOT_DIR (missing: OPENSSL_CRYPTO_LIBRARY
  OPENSSL_INCLUDE_DIR)

  depends/libff/CMakeLists.txt:115 (find_package)

It can be handled by the following commands:

$ brew upgrade openssl
$ brew link --force openssl
$ pkg-config --modversion openssl

I think it will be helpful for the new comings.
