I think generator expressions in test properties are not supported in 
2.8.12.2 (current release).

Can you try with 3.0-rc4?

Escaping the semicolons should work.
e.g. (untested):

  string(REPLACE ";" "\;" ESCAPED_PATH "$ENV{PATH}")

  set_property(TEST mytest PROPERTY ENVIRONMENT
      "PATH=${ESCAPED_PATH}\;baz\;$<TARGET_FILE_DIR:foo>"
  )
