Cmake error at find packages to finish the build

Question

I want to build easyhttp - https://github.com/sony/easyhttpcpp/wiki/Installing-EasyHttp#build-easyhttp and after Cmakeing, it doesn't find packages to finish the build

CMake Error at /usr/local/lib/cmake/Poco/PocoConfig.cmake:29 (find_package):
  Could not find a package configuration file provided by "PocoNetSSL" with
  any of the following names:

    PocoNetSSLConfig.cmake
    poconetssl-config.cmake

  Add the installation prefix of "PocoNetSSL" to CMAKE_PREFIX_PATH or set
  "PocoNetSSL_DIR" to a directory containing one of the above files.  If
  "PocoNetSSL" provides a separate development package or SDK, be sure it has
  been installed.
Call Stack (most recent call first):
  CMakeLists.txt:56 (find_package)

Answer 1

The POCO Core library doesn't include the PocoNetSSL components. So they need to be installed additionally.

With vcpkg run to list the different poco components available:

./vcpgk search poco

You should get an output similar to this:

poco                     1.11.0           Modern, powerful open source C++ class libraries for building network and ...
poco[mariadb]                             MariaDB support for POCO
poco[mysql]                               Mysql support for POCO
poco[netssl]                              NetSSL support for POCO
poco[pdf]                                 Haru support for POCO
poco[postgresql]                          PostgreSQL support for POCO
poco[sqlite3]                             Sqlite3 support for POCO

To insatll poco[netssl] with vcpkg run:

./vcpgk install poco[netssl] --recurse

When using vcpkg don't forget to integrate the installed libraries to make them available:

./vcpkg integrate install
