What is it?

Every Hunter release (Atom feed) archive is a meta-package with build instructions and URLs of real packages. Archive will be downloaded and unpacked automatically by HunterGate CMake module. You only need to set URL and SHA1:

HunterGate(
    URL "https://github.com/ruslo/hunter/archive/v0.14.5.tar.gz"
    SHA1 "f2c3de6d13baf8c5d2aa77bdc47c516e668c677e"
)

Here is content of the archive in simplified form:

Hunter (0.14.15) = {
    Boost (1.60.0, 1.59.0, 1.58.0-p1, ...),
    GTest (1.7.0, ...),
    OpenCV (3.0.0-beta, 2.4.11, 2.4.10, ...),
    OpenSSL (1.0.2g, 1.0.2f, 1.0.2e, ...),
    ...
}

If you download and unpack it you can view some internals. Let’s see OpenSSL package properties:

wget https://github.com/ruslo/hunter/archive/v0.14.5.tar.gz
tar xf v0.14.5.tar.gz

hunter.cmake holds list of available versions:

grep -A3 -m3 VERSION hunter-0.14.5/cmake/projects/OpenSSL/hunter.cmake

    VERSION
    "1.0.2g"
    URL

Install instructions from build scheme url_sha1_openssl.cmake.in:

grep -A1 INSTALL_COMMAND hunter-0.14.5/cmake/projects/OpenSSL/schemes/url_sha1_openssl.cmake.in

INSTALL_COMMAND
make install_sw

Default version from default.cmake (is customizable, see Config-ID):
