Posix regex not found. Other regex produces compilation errors

This is for googletest release 1.11.0 Compiling on MacOs Catalina Trying to compile this sample code:

#include "gtest/gtest.h"

// Demonstrate some basic assertions.
TEST(HelloTest, BasicAssertions) {
    // Expect two strings not to be equal.
    EXPECT_STRNE("hello", "world");
    // Expect equality.
    EXPECT_EQ(7 * 6, 42);
}

Initially produced these errors:

/Users/jsaremi/install_folder/include/gtest/internal/gtest-port.h:929:3: error: unknown type name 'regex_t'
  regex_t full_regex_;     // For FullMatch().
  ^
/Users/jsaremi/install_folder/include/gtest/internal/gtest-port.h:930:3: error: unknown type name 'regex_t'
  regex_t partial_regex_;  // For PartialMatch().
  ^

I tried disabling the POSIX option by including these lines prior to "gtest.h". That did not work:

#define GTEST_USES_SIMPLE_RE 1
#define GTEST_USES_POSIX_RE 0

then I tried the following:

#define GTEST_USES_PCRE 1
#define GTEST_USES_SIMPLE_RE 1
#include "gtest/gtest.h"

This time I got the following errors:

                       : RE::PartialMatch(s2, *regex_);
                         ^

What is the rightway of ensuring that Regex code compiles?

Thanks

Please provide the full details (commands etc) on how you are building and installing GoogleTest.

[jeffsaremi]

I have built this using CMake with the following flags:

                  "-DCMAKE_PREFIX_PATH=" + runprefix,
                  "-DCMAKE_INSTALL_PREFIX=" + runprefix,
                  "-DCMAKE_INSTALL_LIBDIR=lib",
                  "-DCMAKE_POSITION_INDEPENDENT_CODE=TRUE",
                  "-DBUILD_GMOCK=ON",
                  "-DINSTALL_GTEST=OFF",

And since "make install" did not seem to be available I used the following equivalent to install it:

          cmd_install=[
              ["COPY"] + ["lib/libgtest.a", os.path.join(runprefix, "lib")],
              ["COPY"] + ["lib/libgmock.a", os.path.join(runprefix, "lib")],
              ["COPY"] + ["lib/libgtest_main.a", os.path.join(runprefix, "lib")],
              ["COPY"] + ["lib/libgmock_main.a", os.path.join(runprefix, "lib")],
              ["CD", "googletest/include"],
              ["COPYALL"] + [os.path.join(runprefix, "include")],
              ["CD", "googlemock/include"],
              ["COPYALL"] + [os.path.join(runprefix, "include")],
          ],

I'm also compiling on Catalina and I couldn't reproduce the issue anymore.
