When trying to compile code (using cmake), I keep getting this error :
In file included from /usr/local/include/cpprest/http_client.h:68:

make[2]: *** [CMakeFiles/httpclient.dir/http_client.cpp.o] Error 1
make[1]: *** [CMakeFiles/httpclient.dir/all] Error 2
make: *** [all] Error 2
I have tried to follow these links but nothing helps : Fatal Error: 'openssl/conf.h' file not found and 'openssl/conf.h' file not found error on on MacOS Big Sur and 'openssl/conf.h' file not found error on MacOS Sierra
Following is my cmake :
cmake_minimum_required(VERSION 3.9)
find_package(cpprestsdk REQUIRED)
set (CMAKE_CXX_STANDARD 11)
add_executable(httpclient http_client.cpp)
set(OPENSSL_ROOT_DIR /usr/local/opt/openssl@3)
#set(OPENSSL_LIBRARIES /usr/local/opt/openssl@3/lib)
set(OPENSSL_ROOT_DIR /usr/local/opt/openssl@3/*)
set(OPENSSL_LIBRARIES /usr/local/opt/openssl@3/lib)
include(FindOpenSSL)
target_include_directories(httpclient INTERFACE ${OPENSSL_ROOT_DIR}/include)
target_link_libraries(httpclient PRIVATE cpprestsdk::cpprest
openssl)
I have also tried setting LDFLAGS and CPPFLAGS, it din't help. Also tried re-installing boost - din't work.
Please help me understand how to resolve this.
Thanks!
